The star Betelgeuse in Orion has brighten and is once again a bright star. Use this AAVSO star chart to compare Betelgeuse to other bright stars of Orion. 

AAVSO Betelgeuse wide file 10 star tutorial project chart.

AAVSO Orion Constellation centered on Betelgeuse. Belt stars near bottom. 

 

NEW Comet C/2020 F8 SWAN discovered, currently visible in Southern Hemisphere at magnitude 8. (Will be seen locally in the morning sky in first weeks of May 2020)

Visible in the morning sky between end of darkness and start of twilight. R. Close approach to the Sun (perihelion) is on May 27, 2020, when the comet is some 5 degrees above the horizon in late twilight.  This is not the best viewing condition from our neck of the woods, but one can only hope for clear skies and good horizons. 

5/31/2020  C/2020 F8 Swan has dimmed and will NOT be bright.
